WATER-CLOSET FLUSHlNG-VALVE.

SPECIPIECATION forming part of Letters Patent No. 351,835, dated Novernber 2 1886.

' Application filed March 30, 1886. Serial No. 197,145.

To all whom it may concern.-

Be it known that I, FRANCIS WILLIAM KELLY, a citizen of. the United States, and a resident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in- Water-Oloset Flushing-Valves, of which the following specification is a full, clear, and exact description, reference being also had to the aet; companying drawings, in which- Figure 1 is a sectional side view on the line as x ofrFig. 2. Fig. 2 is a cross'sectional view on the line 1 y of Fig. 1; and Fig. 3 is a plan view, with the cover removed, of the flushingtank and receiving-bowl with my improved valve mechanism arranged in said tank. Fig; 4 is an enlarged sectional elevation of the valve-casing and valves. v

A represents the tank for holding the flushing-water; A", the deposit-bowl, the bowl and tank being connected by large pipe A, through which the water from the tank rushes into the bowl. A is the soil-pipe leading from the bowl A U to the sewer-connection A the latter also connected to the tank A and with a large valve, A, adapted to close the exit into the sewer. This valve has a stem, or, running up through the cover of the tank andprovided with a handle, a by which it may be raised. .The exit b from the bottom of the tank A is about the same size as and directly above the valve A", so. that when the latter is raised 'up it will close the bottom exit, b, of the tank and cause all the water in the tank to flow through the connection A into the bowl, and from thence into the sewer-connection through the soilpipe A. p

represents the overflow partition and trap, which is placed in one corner of the tank A, as shown in Figs. 2 and 3, and which is connected, as shown at g in Figs. 2 and 3, with the sewer-connection A l B represents a valve-casing united throughthe bottom of the tank A by a connection, B, to the water-supply pipe B the latter taking its water from the hydrant or a large tank above, or from any other suitable source.

Bjs a side branch leading from the side of the casing B, and towhich the flush-pipe B is connected. This flush-pipe is shown passing out through the side of the tank at d and (No model.)

continued into the upper edge of the depositbowl A in theordinary manner.

e is a val ve-seat in the casing B, just beneath the opening into the side branch, B, and beneath which a valve, 6 is adapted to be seated. This valve 6 is screwed upon a tubular stem.

e*, which passes up ward above the valve e*, and

is supplied with a piston-head, e, working water-tight against the inner sides'of the easing B.

D is a rod passing down through the tubular stem 6 and provided on its lower end with asmall valve, D adapted to be seated upon the lower end of the tubular stem 6 and with a guide, D, in the connection B for its lower end.

The rod Dis smaller than the interior of th tubular stem 6 so that water can pass up through the tube around the rod, and to keep the tube in position around the rod when the valve e is open the rod is shown provided with small projections g, which press against the tube and keep the rod centrally therein. The 7 5 upper end of this rod D passes out through a stuffing-box, D, in the cover D of the casing B, and is provided on its upper end, outside the cover D, with a head, D in which the float-rod Ev is pivoted. vThe shorter end of this float-rod is pivoted at E to the cover D or to any other fixed part of the valve-casing,

,while the long end is connected to the float E.

F is a small pipe tapped into the valve-casing B above the piston e, and bent down into the outer pocket or trap of the overflow 9, so that the water in the overflow will be renewed withfresh water every time the valve is operated.

This tank is more particularly applicable to 0 the form of water-closet shown in my Patent in the tank and bowl at a height sufficient to hold the float E high enough to keep the rod D elevated, and thus keep the valves e and D closed, as shown in Fig. 4. Then, when the main valve A? is opened, the water falling in the tank will cause the float E and its rod E to also fall and push the rod D downward, and thus open the valve D and allow the water to rush up through the tubular stem 6 into equalizing-chamber B above the diaphragm or piston-head e", and when a sufficient quantity of water has accumulated therein to overcome the inertia of the piston the latter and the tubular stem 0 will be forced downward and open the larger valve, e", and allow the water to pass into the side branch, B, and thence through the flush-pipe B into the bowl to flush it and replenish it with fresh water. The water will thus continue to flow through the valve 6" until the main valve is closed and the water has risen in the tank and bowl to a height sufficient to raise the float E high enough to cause its rod E to raise the rod D, and thus close the valves (2 D". In the meantime the water which passed into the equalizingchamber B when the Valve D was first opened flows out through the small pipe F and renews the water in the overflow I). The pipe F must be small enough so that the water will flow through it veryslowly, so as not to interfere ith its proper action on the piston 0*. By this simple arrangement the replenishing of the tank and bowl is automatically secured by the combined action of the float and double valves D 7 An important advantage gained by this construction is that a very slight movement of the float and the expenditure of a very small amount of power only is required to operate the valves, it being necessary to open and close the valve D only, the other valve, 0 operating entirely by the action of the water in the equalizing-cl1ainber and being independent of the float.

Having described my invention and set forth its merits, what I claim isl. The combination of a valve-casing, B, inserted into the flush-tank A, and having a side branch, B and inletpipe B at its lower end, and with a valve-seat,e, below said side branch, a valve, 6 adapted to be seated upon said valve-seat, and with a tubular stem, e, having a piston, e, adapted to fit the interior of said casing above said valve-seat and form an equalizingchamber, B, in said casing, the pipe F, leading into the said equalizing-chamber, rod D, passing down through said tubular stem, and having valve D,adapted to be seated upon the lower end of said tubular valve-stem, and a float adapted to be raised and lowered by the rising and falling water in said tank to depress and elevate said rod D, and thus open and close said valve D and permit the water to enter said equalizingchamber and open said valve 6 substantially as described, and for the purpose set forth.

2. The combination, with the tank A, having overflow g, of the valvecasing B, set into said tank and connected to the inlet-pipe B, side branch, B, leading from said valve-casing and connected to discharge-pipe B, valveseat e within said casing, valve e adapted to be seated upon said valve-seat and having tubular stem 0, passing upward through said cas ing, piston e on the upper end of said tubular stem and fitting the interior of said casing, rod D, passing downward through said casing and tubular stem, and having valve D on its lower end, adapted to be seated upon the lower end of said tubular stein, rod E, pivoted to the upper end of said rod 1) and having float E, and pipe F, adapted to replenish said overflow, all operating substantially as described, and for the purpose specified.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
